Research And Application For Graphical User Interface Of Lead-Acid Battery's State Of Charge Inspection System

This thesis is based on the inspection system, which is used for forecasting the State of Charge (SOC) of lead-acid battery. This thesis mainly introduces the research and design of Graphical User Interface (GUI) in ARM Linux operating system, discussing the theory, technology and the applications of GUI, and put the focus on the Qt/Embedded system.This thesis firstly introduces the hardware platform of this inspection system. This system takes the top and bottom machine configuration, and the top machine system uses the Samsung S3C2410 ARM as the processor and adopts Linux operating system.Secondly, explains the technology used in this system, and analyses the thought of design and basic principle of GUI in embedded system. Thirdly, this thesis compares some popular kinds of GUI system, especially in performance and realization. Finally, makes the deep research in the advanced technology of Qt/Embedded system.The mode of GUI inspection system is also the significant part of this thesis. The thesis introduces the"Target-Host"developed mode in embedded operating system and the remote debugging, the installing and cross compiling of Qt/Embedded and the configuration and installing of frame buffer server.The function of inspection system for forecasting the SOC of lead-acid battery should be confirmed in the first place, and then make the research and development of this system based on the function. This system is made up of three parts: showing and storaging data, the program for forecasting the SOC and real time communication. This thesis discusses the process of each mode and the used technology, introduces in detail the important role of Qt in the research and development.At the end, this thesis summarizes the accomplishment and prospects the future of this work.
